FCAW · Carbon steel
E71T-11
A general purpose gasless wire with a smooth spray-type arc, common on small machines and light fabrication where no impact toughness requirement applies.
What the designation means
Point at any character to see what it claims. The classification is a sentence written in fields, not a product name.
- EElectrode carrying the welding current.
- 770,000 psi minimum tensile strength of the deposit.
- 1All position capability.
- TTubular flux cored construction.
- -11The usability class: a general purpose self-shielded flux run on direct current electrode negative, with no impact toughness requirement and a thickness limit on multipass work.

Typical uses
- Light fabrication and repair on small portable machines
- Farm, fence, and trailer work outdoors
- General purpose welding on thin to medium carbon steel
How it runs
- Smooth spray-type arc that is easy to control at low current
- No shielding gas needed, so it works in wind
- Carries no notch toughness requirement, and multipass use is limited by thickness
- Slag is easy to remove but the process smokes noticeably
Storage and handling
Keep in sealed packaging with desiccant and rebag opened spools; a damp flux core causes porosity and a spitting arc.
